This CLR input also serves as a trigger input when it is pulsed with a low level pulse transition.

Monostable Multivibrator

In most applications, pulse stability will only be limited by the accuracy of external timing components. I CC Supply Current. Each device has three inputs permit- ting the choice of either leading-edge or trailing-edge trig- gering. Output pulse width may be varied from 35 nanoseconds to a maximum of 70 s by choosing appropriate timing components.

The DM74LS is a dual monostable multivibrator with. Additionally an internal latching circuit at the datsaheet stage also provides a high immunity to V CC noise. You may also be interested in: Pulse triggering occurs at a voltage level and is not related to the transition time of the input pulse.

If pulse cutoff is not critical, capacitance up to mF and daatsheet as low as 1. Input pulse width may be of any duration relative 74l221 the output pulse width.

Each multivibrator of the 74LS features a negative-transition-triggered input and a positive-transition-triggered input either of which can be used as an inhibit input. Order Number Package Number. Jitter-free operation is maintained over the full temperature and VCC ranges for greater than six decades of timing capacitance 10 pF to 10 mFand greater than one decade of timing resistance 2.
